Appearance
In this article, you will find information about the styling options and rendering of the Kendo UI FloatingActionButton.
For a live example, visit the Appearance Demo of the FloatingActionButton.
Options
The Kendo UI FloatingActionButton supports the following styling options:
-
size—configures the overall size of the component. -
fillMode—configures how the color is applied to the component. -
themeColor—configures what color will be applied to the component. -
rounded—configures the border radius of the component.
Size
The size option controls how big or small the rendered FloatingActionButton looks. The structure of the class is k-fab-{size}.
The following values are available for the size option:
-
sm—small size -
md—medium size -
lg—large size -
none—unset
The following example demonstrates how to configure the size of the component through the component configuration:
<button id="fab"></button>
<script>
$("#fab").kendoFloatingActionButton({
size: "large"
});
</script>
The default size value is medium and it is applied to the wrapping span element through the k-fab-md class.
<button class="k-fab k-fab-sm">
</button>
FillMode
The fillMode option controls the way the color is applied to the rendered FloatingActionButton. The structure of the class is k-fab-{fillMode}.
You can set the fillMode either to solid or to null.
The following example demonstrates how to configure the fillMode of the component through the component configuration:
<input id="fab" />
<script>
$("#fab").kendoFloatingActionButton({
fillMode: null
});
</script>
The default fillMode value is solid and it is applied to the button element through the k-fab-solid class.
<button class="k-fab k-fab-solid" >
</button>
ThemeColor
The themeColor option controls the color that will be applied to the rendered FloatingActionButton. As applying themeColor is closely related to the fillMode, the structure of the class name for the themeColor is composite - k-fab-{fillMode}-{themeColor}.
The following values are available for the themeColor option:
primarysecondarytertiaryinfosuccesswarningerrordarklightinversenone
The default themeColor value is primary. A FloatingActionButton with default fillMode and themeColor will have k-fab-solid-primary class applied.
<!-- FloatingActionButton with default fillMode and themeColor -->
<button class="k-fab k-fab-solid-primary k-fab-solid" >
</button>
<!-- FloatingActionButton with 'primary' themeColor and fillMode set to null -->
<button class="k-fab" >
</button>
<!-- FloatingActionButton with `solid` fillMode and `success` themeColor -->
<button class="k-fab k-fab-solid-success k-fab-solid" >
</button>
Rounded
The rounded option controls how much border radius is applied to the rendered FloatingActionButton. The structure of the class is k-rounded-{size}.
The following values are available for the rounded option:
-
sm—small border radius -
md—medium border radius -
lg—large border radius -
full—largest border radius -
none—unset
The example below demonstrates how to configure the rounded of the component through the component configuration:
<input id="fab" />
<script>
$("#fab").kendoFloatingActionButton({
rounded: "large"
});
</script>
The default rounded value is full and it is applied to the button element through the k-rounded-full class.
<button class="k-fab k-rounded-full" >
</button>
Rendering
Starting with version R1 2022, the component has a new rendering. For additional information on the decision behind these changes, visit the Components Rendering Overview article.
To review the latest rendering of the component, refer to the HTML specifications in the Kendo UI Themes Monorepo. The tests folder of the repository contains the rendering for all flavors of the components, providing a clear reference for how their elements are structured. The rendering information can help you customize a component's appearance and behavior by applying custom CSS or JavaScript to suit specific design or functional requirements.
Best Practices
The Material Design guidelines dictate that:
When you configure the FloatingActionButton to display additional related actions (speed dial actions), you should configure only an icon for the button, without a label. Use labels to display additional information for the related actions.
If the application requires an icon and a label for the Kendo UI FloatingActionButton, consider omitting the additional actions.
<div id="fab"></div>
<script>
$(document).ready(function () {
$("#fab").kendoFloatingActionButton({
icon:"plus",
text: "Add To Cart"
});
});
</script>
Icons
The icon configuration option specifies the name of an icon. The selected icon must be available in the Kendo UI theme that is rendered by the FloatingActionButton. For more details on the available Web Font icons see the Web Font Icons article.
<div id="fab"></div>
<script>
$(document).ready(function () {
$("#fab").kendoFloatingActionButton({
icon:"plus",
items:[
{icon:"star",label:"Add Rating"},
{icon: "pencil", label:"Add Comment"}
]
});
});
</script>
